[Standardized histomorphological processing of peritoneal biopsies as part of the German Peritoneal Biopsy Registry (GRIP, German registry in PD)].

The peritoneal lining of the abdominal cavity consists of a parietal and visceral sheet. The serosa is an interesting organ, which in medical practice is particularly important in the context of chronic peritoneal dialysis (PD). This method of renal replacement therapy utilizes the semipermeability of the peritoneal surface by applying PD solutions of differing osmolarity to eliminate toxic substances and regulate fluid and electrolyte equilibrium.

Benefits of peritoneal ultrafiltration in HFpEF and HFrEF patients.

Background: Peritoneal ultrafiltration (pUF) in refractory heart failure (HF) reduces the incidence of decompensation episodes, which is of particular significance as each episode incrementally adds to mortality. Nevertheless, there are insufficient data about which patient cohort benefits the most. The objective of this study was to compare pUF in HFrEF and HFpEF, focusing on functional status, hospitalizations, surrogate endpoints and mortality.

Peritoneal dialysis as therapeutic option in heart failure patients.

Aims: Each episode of acute decompensated heart failure (HF) incrementally adds to mortality. Peritoneal dialysis (PD) offers an alternative therapeutic option in refractory HF and reduces the incidence of decompensation episodes. The objective of this study was to determine the efficacy of PD, in terms of functional status, surrogate endpoints, rate of hospitalizations, and mortality.

Preparative and electrochemical investigations on the electron sponge behavior of cobalt telluride clusters: CO substitution in [Co11Te7(CO)10]n- ions (n=1, 2) by PMe2Ph and crystal structure of [Co11Te7(CO)5(PMe2Ph)5].

The reaction of the cluster salts [Cp(2*) Nb(CO)(2)](n)[Co(11)Te(7)(CO)(10)] (Cp*=C(5)Me(5); n=1, 2) with excess PMe(2)Ph gave the neutral, dark brown clusters [Co(11)Te(7)(CO)(6)(PMe(2)Ph)(4)] (5) and [Co(11)Te(7)(CO)(5)(PMe(2)Ph)(5)] (6) with 147 metal valence electrons. The new compounds were characterized by IR spectroscopy, elemental analyses, and mass spectrometry. The molecular structure of 6 was determined by X-ray crystallography.

An update on regulatory issues in antidoping programs in sport.

Doping control for national- and international-level athletes has undergone major changes in the past few years, and will continue to change at an accelerated rate. National antidoping organizations (NADOs) such as the United States Anti-Doping Agency (USADA) are being established by major nations to work with national governing bodies of sport. The World Anti-Doping Agency has been established to coordinate worldwide antidoping efforts with the NADOs and international federations of sport, and to implement a recently drafted World Anti-Doping code, which clarifies the definition of doping and establishes procedures to harmonize international efforts in sample collection process, testing laboratory accreditation, result reporting, and result adjudication.

[{(tBuC H ) Nb(CO)} Co (CO) Te ⋅3 Cr(CO) ]: Unusual Stabilization of a Cubic Body-Centered Metal Telluride Cluster by Peripheral Complex Fragments.

The Te bridges of the [Co (CO) Te ] cube of 1 serve as anchors for three Cp$\rm{^{\prime }_{2}}$Nb(CO) (Cp'=tBuC H ) and three Cr(CO) fragments. This new principle allows the synthesis and structural comparison of clusters with 122-124 metal valence electrons.

Metal telluride clusters composed of niobocene carbonyl, telluride, and cobalt carbonyl units: syntheses, structures, and reactivity.

Abstract: The reaction of [Cp#2NbTe2H] (1#; Cp# = Cp* (C5Me5) or Cp(x) (C5Me4Et)) with two equivalents of [Co2(CO)8] gives a series of cobalt carbonyl telluride clusters that contain different types of niobocene carbonyl fragments. At 0 degrees C, [Cp#2NbTe2CO3(CO)7] (2#) and [Co4Te2(CO)10] (3) are formed which disappear at higher temperatures: in boiling toluene a mixture of [cat2][Co9Te6(CO)8] (5#) (cat= [Cp#2Nb(CO)2]+) and [cat2][Co11Te7(CO)10] (6#) is formed along with [cat][Co(CO)4] (4#). Complexes 6# transform into [cat][Co11Te7(CO)10] (7#) upon interaction with HPF6 or wet SiO2.

[Membranoproliferative glomerulonephritis in non-Hodgkin's lymphoma nad myeloproliferative syndrome--a causal relationship?].

A pathogenetic relationship is postulated for the development of membranoproliferative glomerulonephritis type I in non-Hodgkin's lymphoma (B-cell lymphoma of low-grade malignancy) and myeloproliferative syndrome, which we have observed in eight patients. This hypothesis is supported by the fact that chronic lymphatic leukaemia and immunocytoma are often associated with immunodysregulative phenomena, and by the immunohistological and ultrastructural findings in the kidney, especially the frequent electron-microscopic finding of cryoglobulins, which results in the membranoproliferative type of immune-complex glomerulonephritis, an expression of a disturbance in immune balance. The pathogenetic mechanism may involve cryoglobulins themselves as immune complexes; it is also possible that monoclonal cryoglobulins combine with an antigen to form immune complexes or lead to in situ formation of immune complexes.
